2.12.3.3. Link Fault Configuration

Offset: 0x405

Link Fault Configuration Fields

Bit Name Description Access Reset
3 force_rf Force the TX MAC to transmit Remote Faults when link fault signaling is on

1: TX MAC transmits Remote Faults

0: TX MAC operates normally

RW 0x0
2 disable_rf Send idles instead of remote faults for local faults in unidirectional mode

1: In unidirectional mode, local faults cause the TX to transmit Idles

0: In unidirectional mode, local faults cause the TX to transmit Remote Faults (spec default)

RW 0x0
1 en_unidir Enable Unidirectional Link Fault
1: EHIP enables support for unidirectional link fault signaling as described in Clause 66 Remote faults have no impact on TX data, and Local faults causee the TX to transmit Remote fault Ordered sets between frames
  • After power-on, en_unidir is set to 0
  • After i_csr_rst_n, en_unidir is set according to the module parameter link_fault_mode
RW 0x0
0 en_lf Enable Link Fault Reporting
1: The TX PCS transmits link fault messages based on link faults detected by the RX
  • After power-on, en_lf is set to 1'b1
  • After i_csr_rst_n, en_lf is set according to the module parameter link_fault_mode

0: The TX PCS does not respond to link faults

RW 0x1
